Single tooth loss – bidge or implant?
There is no type of augmentation that can entirely replace a natural tooth. They all have their faults, whether crown, denture or implant. This text should simplify your choice between crowns and implants.
THREE UNIT BRIDGE
A bridge requires filing down of the carrier tooth. If the teeth are healthy, undamaged, without any caries, it is clear that a bridge would cause harm in that case, which is why implants are more beneficial.
Tooth filing sometimes requires previous endodontic treatment. During this treatment, blood vessels are removed, among other things, i.e. the flow of nutrients needed for the natural regeneration of tooth tissue is stopped. This kind of tooth becomes more brittle and susceptible to caries.
The crown that replaces the tooth “hangs” between two carrier teeth and as such doesn’t have contact with the tooth bone and supporting tooth pulp, so that there are no biting force effects and the bone and gums start to recede.
Dental prosthetics with crowns do not last forever. Whereby we do not mean the lifespan of the crowns themselves but the lifespan of the carrier teeth. Even though they are protected by the crowns, they are still susceptible to caries and periodontitis, which causes tooth bone and gingiva to recede.
Problems can be overcome with good maintenance, but that is rarely the case. After all, bridges have to be replaced within an optimal time period so that, after we remove the old bridges, we can find the carrier teeth and surrounding tissue in a good enough state for the creation of new prosthetics. The optimal deadline for the replacement of an old bridge is 7 years, or 10+ years in our country. Unfortunately, regular maintenance in the form of dental checkups and professional cleaning is usually forgone.
Placing a crown or a bridge on an implant does not require tooth filing, which is a great advantage, especially when healthy neighboring teeth are concerned.
There is no possibility of the need for endodontic therapy arising for the filed-down teeth, which can be the case with bridges.
Biting forces are transferred through the implant, installed into the bone, onto the bone itself and surrounding supporting tissue. As a result of the effects of these forces, there is no bone loss in most cases or it is much lower (almost unnoticeable) than the bone loss occurring in cases when the crown “hangs between two carrier teeth” and there is no transfer of forces onto the tissue beneath.
Prosthetics placed on implants also have their lifespan. A properly placed implant lasts a lifetime and only the crown itself has to be replaced. Since the surrounding teeth aren’t filed-down, their condition doesn’t affect the lifespan of the dental prosthetics. That is why work done on implants lasts longer.
